These findings suggest that clinical trials in humans with alcoholic liver disease should be considered. The report appears in the August 2015 issue of the Journal of Leukocyte Biology.http://medicalxpress.com/news/2015-07-gout-medications-alcohol-induced-liver-disease.html

The group outlines their research efforts and results in the journal Science. French medical researchers Laurence Zitvogel and Guido Kroemer offer a PERSPECTIVE piece on the work done by the team in the same journal edition.http://medicalxpress.com/news/2015-07-tumor-suppressor-p53-signaling-mediated-phagocytosis.html

But that finding naturally begs more questions about what these noncoding regions do to cause a disease and how.http://medicalxpress.com/news/2015-07-juvenile-arthritis-genetic-genes.html

Those with strong immune systems, however, appeared to benefit from waiting until after the end of the six-month TB treatment before initiating anti-HIV therapy.

Chronic inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease are associated with behavioral symptoms that include fatigue, depression, and social withdrawal. Researchers at the University of Calgary fed probiotics to mice with liver inflammation and found that the treatment reduced these behaviors.http://medicalxpress.com/news/2015-07-probiotics-behavioral-symptoms-chronic-inflammatory.html

Vaccinated mice produced broadly neutralizing antibodies against multiple strains of the MERS coronavirus (MERS-CoV), while vaccinated macaques were protected from severe lung damage when later exposed to MERS-CoV. The findings suggest that the current approach, in which vaccine design is guided by an understanding of structure of viral components and their interactions with host cells, holds promise for developing a similar human MERS vaccine regimen.http://medicalxpress.com/news/2015-07-experimental-mers-vaccine-animal.html

WNV infection turns serious when the virus crosses the blood-brain-barrier and wreaks havoc among nerve cells in the brain. A study published on July 23rd in PLOS Pathogens suggests that several critical components of the early immune response to the virus are impaired in elderly individuals, and that this can explain their vulnerability.http://medicalxpress.com/news/2015-07-west-nile-virus-dangerous-elderly.html

What physicians know as "acute lung injury" (ALI) otherwise leads to death by suffocation without immediate treatment. This is due to water retention in the lung tissues (oedemas) and to a massive inflammatory response that, in the end, destroys lung tissues and hinders gas exchange. This acute lung injury (ALI) is treated through artificial respiration and anti-inflammatory cortisone.http://medicalxpress.com/news/2015-07-cortisone-affects-acute-lung-injury.html
